need some suggestions

currently running halo/mdrol about 5days in. i think wk2 i might add test-e, thing is the mdrol is stacked with the hdrol for 6wks like this mdrol 10/10/20
hdrol 2wks 75 and 4wks 100
the test would only be able to be run for 300mg for 10wks or 375 for 8wks. my friend is givin me a free vial that he's not using and i have no source. should i just wait til either myself or him find another source so i can run 500mg for 12wks or worst case scenario sell it myself. i just would love to run test again but dont wanna waste it either.
